' accompanyingdrawings.

My invention relates to automobiles, and is especially well adapted for use in connection with the type propelled by gas-engines. It is well understood that in using gas-enginesit is necessary to circulate water around the engine-cylinder to reduce the excessive heat and prevent premature explosions of the gases,

and it frequently happens in using automobiles of. this class. in cold climates that the circulating water freezes, with disastrous effects tothe circulating system. This leads to great annoyance andalways occasions con- ;fsidera'ble delay in starting the machine.

The object of this invention is to provide a simple means for quickly putting the circulating system intact in case of an accidental freezing.

The invention consists in a certain arrangement and combination ofparts to be more fully described hereinafter and definitely set forth in the claims.

In the drawings, which fully illustrate my invention, Figure 1 represents, in side elevation, somewhat diagrammatically an automobile to which my invention has been applied. Fig. 2 represents a detail of the invention in longitudinal vertical section.

.sents the body of an Referring to the parts by letters, A repreautomobile in side elevation, carrying a gasengine B, adapted to propel the vehicle in the usual manner by means of the connecting-rod b and crank c,

I voir F is carried by the.vehicle, preferably on the lower side of the body toward the front, as indicated. This reservoir contains circulating water and constitutes a radiator also for cooling the same.

ranged a suction-nozzle G, the construction of which will be more'fully described later. This nozzle connects by means of the pipe g with the inlet-opening of the aforesaid rotary pump E. From the outlet-opening of the pump a section of pipe 0 leads the waterv to the engine-cylinder wall, through which it circulates in the well-known manner, findingexit through the return-pipe H. This return-pipe is arranged so that it inclines downward toward the front of the vehicle, wherefore the water is adapted to drain by gravity in that direction, and its extremity is provided with water within the reservoir F. In this -manner while the machine is in motion water is continuously circulated about the engine-cylinder for the purpose mentioned. Referring especially to Fig. 2, it will appear that this nozzle having an inner tube or duct 7, which passes from the bottom to the top of the same and connects at its upper extremity with the aforesaid suction-pipe g. In this manner an inner duct is formed, surrounded by a chambe xg rearwardly into the mufiler K, which is of any suitable construction, whence they are led by the pipe is toward the front of the vehicle. This pipe connects at its extremity, as indicated, with the aforesaid chamber g. An outlet-pipe g is provided, which leads from this chamber and is adapted for carrying the exhaust-gases to the open air. In this'man ner the exhaust-gases be made to circulate through the chamber g and if the water within the reservoir F should befrozen they quickly melt the ice in the neighborhood of the suction nozzle. 'The small amount of water which is produced in this manner is immediately drawn away by the pump, circulated about the engine-cylinithin'it is ar The exhaust-gases from thecylinder Bpass from the engine may a downward extension 7b., which delivers the a consists of a substantially cylindrical body the exhaustgases either toward the suctionnozzle or to allow'them to exhaust into the open air through the outlet-pipe Z. This arrangement allows the operation of melting the ice to be discontinued as soon as it is no longer necessary. I

It will be observed that the reservoir F is located at the lowest level of the circulating system and the piping and connections-are so arranged that when the vehicle is standing idle the water of the system will drain into the reservoir.

What I claim is r 1. In an automobile, in combination, an engine adapted to propel the vehicle, a watercirculating system, a reservoir forminga part of said system and located at a lower level than any other point in said system, pipes leading to and from said reservoir, one of said pipes extending into said resevoir, and means for passing the exhaust-gases from said engine around said pipe extending into said reservoir, substantially as described.

2. In an automobile, in combination, a gasengine adapted to propel the vehicle, a watercirculating system including a reservoir in which the water of said system may collect, a suction-nozzle through which the water from said reservoir may be drawn, and means for circulating the exhaust-gases from said engine around said nozzle, substantially as set forth.

3. In an automobile, in combination, a gas engine adapted to. propel the vehicle, a watercirculating system adapted to lead water around the cylinder-wall of said engine, a reservoir in said circulating sytem in which the water may collect, a suction-nozzle through which the water from said reservoir maybe drawn, and means for circulating the exhaustgases from said engine around said nozzle,

substantially as set forth.

4. In an automobile, a gas-engine adapted to propel the vehicle, a water-circulating system adapted to lead water around the cylinder-wall of said engine, a pump adapted to maintain said water in circulation while said vehicle is in motion, a reservoir included in 5. In an automobile, in combination, an en- -let, substantially as set forth.

6. In an automobile, in combination, a gasengine adapted to propel the vehicle, a watercirculating system adapted to supply water to the jacket of said engine, areservoir forming a part of said system and located at a lower level than any other point in said system wherefore the water may accumulate therein, means for leading the exhaust-gases from said engine through said reservoir, and means intermediate of the engine and said reservoir for permitting the escape of said gases, substantially as described.

7. In an automobile, in combination, a gasengine, a water-circulating system including a reservoir at a low level in said system wherefore the water may accumulate therein, a su ction nozzle within said reservoir, through which the water of said reservoir may be drawn, said suction-nozzle comprising an inner duct and a chamber surrounding the same, and means for leading the exhaust-gases from said engine through said chamber, substantially'as set forth.

8. In an automobile, in combination, a gasengine adapted to propel the vehicle, a watercirculating system adapted to lead water around the cylinder-wall of the said engine; a mufller receiving the exhaust, a reservoir at a low level and included in said circulatingsystem, said reservoir being of such capacity as to contain all the circulating water of said system, and means for leading the exhaust-gases from said muflier through said reservoir, substantially as set forth.

9. In an automobile, in combination, a gasengine adapted to propel the vehicle, a watercirculating system including a reservoir in which the Water of said system may accumulate, a muffler into which the exhaust-gases of said engine may pass, a pipe leading from said muffler through said reservoir, a branch outlet connecting with said pipe and leading directly to the open air and a two-way cock adapted to direct the gases from said muflier to said reservoir or through said branch outlet, substantially as set forth.

10. In an automobile, in combination, awater-circulating system, a nozzle ad ted to have the circulating water drawi therethrough, means whereby the water may-accumulatc thereabout whenxnot. circulating,
